COIN-CONTROLLED APPARATUS.

a citizen of the United States, residing at.

Chicago, in the county of Cook and State of Illinois, have invented a certain new andi useful Improvementin Coin-Controlled A paratus, of which the following is a full, car, concise, and exact description, reference being had to the accompanying; drawings, forming a part of this specificatlon. Q

My invention relates to'coin controlled apparatus and more particularly to a coin controlled apparatus adapted for use in vending newspapers. 0 if.

'It is well known that the dally newspapers and Sunday newspapers sell for different prices. A machine for selling papers must therefore be adapted to sell papers at e ther price. It is, therefore, an object of the invention to provide a coin controlled newspa r vending machine which is adapted to sel papers at different .prices and in Which the price may be changed at willbetween certain limits.

It is a further object of the invention to provide a device of the character described which is adapted to sell newspapers at one, two, five, six, and seven cent prices so that papers may be sold for any one of these prices.

It is a further object of the invention to provide a device of the character described in which the paper to be sold is partly disclosed so that the purchaser may now what paper he is to obtain when he operates the machine. It is also a further ob ect to provide a vending machine of the character set forth in which the name of the paper and certain of the head lines on the paper will be visible so that these may serve to attract purchasers to the machine.

It is a further object of the invention to provide a coin controlled newspaper vending machine with a controlling device which will prevent the operator from obtaining, more Application fled larch 22, 1820. Serial No. 887,711.

moved back toward normal position after once started on its delivery stroke untile-the delivery stroke has been completed.

It is a further object of the invention to provide acoin controlled newspaper vending machine wherein all the operative arts are mounted upon a. removable panel 0 the machine so thatthis panel and theoperating parts carried thereby may be removed if the parts get out of order, and replaced by another panel carrying properly adjusted mechanism. i

It is a further object of the invention to provide a device which will preventlthe use of lead slugs or other slugs made of soft material. The device is also designed. to prevent the use of slugs of larger diameter or of greater thickness than'the required coin.

With these and other'objects in view which will become apparent from the detailed description of the device I have disclosed in the drawings one form'which my invention may take which formis the-best known to me at the present time However, it is to be understood that b this specification and the accompanying rawings I do not intend to limit myself to the specific construction disclosed as modificationsin the specific structure may be required in the manufacture 7 used to designate the same parts throughout the several views of the drawings in which F1g. 1 1s a front elevation of a portion of the casing equipped with my improved coin controlled newspaper vending mechanism.

Fig. 9 1s a horizontal section taken approximately on line 9, 90f Fig.- 3.

Fi 10 is a vertical section corresponding The casing is provided with a swinging door 13 which is mounted. upon hingess14. The door is provided with a window15 which exposes a portion ofthe newspaper 16 to view. The door is also provided with a lock 17 whereby it may be securely locked in closed position. The door 13 willlusuallybemade of the same material as the-1casing'12. The

lower edge of the door is cutaway as shown at 18 and this cut away portion accommodates a panel 19 upon which the operating parts are mounted as a unit. 'The panel'19 completely closes the opening 18 as will be clear from Fig. 2. The lower portion of the door 13 is covered by a metal plate 20 which may be removably secured to the door by means of screws 21. The'panel 19 is securely mounted upon this metal plate by means of the screws 22. some of -w ich are shown in Fig. 3 of the drawings. With this construction it will be apparentthat when the screws 21 are removedthe" plate '20 and panel 19 and all the operating mechanism mounted thereon maybe removed as'a" single This is very useful whennthe parts at out of order. The repair man 'doesrnot ave to fix the machine on'the spot but mayreplace the broken mechanism by a new one and take the broken mechanism to the shop for repair.

Bolted to thepanel 19'are-three brackets- 23, 24, and 25. The bracket 24 is provided with a bearing portion 26'which isadapted to slidably receive one" end ofthe o crating rod or slide 27. The'other end of thls rod or slide passes throughb'earing 23 and is free elements have been to slide therein. The rod 27 I is provided with a recess 28 in its upper-surface which recess accommodates a rack 29 which may be secured to the rod in any suitable manner. It is preferred to secure the rack in therecess by means of ordinary screws 30 'so that the rack may beremoved at any time should removal'be necessary. The rod 27 is providedwith a second recess31 in its upper surface which recess is adapted to receive'one edge of a locking plate 32, which locking late. may be secured to rod 27-by means 0 screws 33. The locking late co operates with elements later to-be escribed for'locking. the rod against movement in a horizontal direction.

The bracket 24 is provided with a second bearing portion 34 which has keyed thereto one end of a rod 35, the other end .of which is keyed to the bracket 25 previously referred to. and movable therewith is a pair of arms 36 and 37. "These arms extend in parallel relation and have their upper ends forked as shown at 38 in Fig. 4 to straddle the rod "35. Each arm has a rearward extension 39 and these extensions are connected by means of a pin 40 which pin maintainsrthe arms in spaced relation. anchoring means for one endfof the coiled spring 41, the purpose of which willlater beset forth. The lower: ends of the arms The pinJalso forms an 36 and. 37 may be conveniently secured to the-rod'27 by'means of ordinary pins. The arms 36 and37-sli le freely along. the rod =35." Positioned between the forked ends' of the arms and slidable and rotatableon the rod 35 is the newspaper engaging element .42

which has a downwardly extendingarm side of the depending portion of the element 42 to support member43 duringthe ejecting movement. .The paper engaging element has an upwardly extending arm which is provided with a roller 44 which roller engages a cam-member 45 which cam member is rigidly secured to the panel 19 as shown in Fig. 2 of-the drawings. The-cam is provided with an upwardly inclined portion'46 and a flat spring portion 47. which isnarrower than the portion 46 as shown in Fig. As the rod 27 is moved to the left in Fig'. 2 the roller 44 rides over the spring portion 47.01: the cam 45. When the rollerreaches the end of the cam it is drawn toward-the 'front wall of the casing by means of-spring Fixedly secured to therod27 member 43 to move forwardly and engage the foremost newspaper 16 from the ack.

The papers rest on edge on a suita le support 49. and are held on said support by means of two vertical rods 50 which rods are spaced apart slightly less than the width of the papers so that the edges of the foremost paper rests behind the rod 50. The prongs on'the member 43 engage the newspaper when the rod 27 has reached the limit of its movement to the left. The prongs will therefore engage the paper and draw it out from behind one of the rods 50. This end of the paper will therefore-swing forwardly and the next paper will bear against this rod. When the slide 27 starts to move backwardly. toward its normal position the prongs draw the aper out from behind the other rod 50. Sliortly after the paper is released from the second rod 50 the roller 44 engages the upwardly inclined portion 46 of the cam 45 and rides upon this inclined which meshes with the rac ortion. This causes the member 43 to be rawnaway from the paper and the paper falls down and out through aslot in the bottom portion of the machine. As the slide 27 approaches the end of its movement toward the right in Fig. 2 the roller passes from beneaththe spring portion 47 of the cam and assumes the position shownin Fig. 2. The machine is then ready for another operation. This vending portion of my machine is made the subject matter of a separate application Serial No. 367,710; filed Mar. 22, 1920, and will not be claimed in this application except in so far asit cooperates with the coin controlled mechanism now to be described. 1

The screws 22 above referred to 'pass through the panel 19, the plate 20 and into threaded openings in the front plate 51 as will be clear from Fig. 4 of the draw ings. This front plate is provided with a plurality of slots 52, 53 and 54. The slots 52 and 53 are of a size to receive one cent pieces while the slot 54 is slightly larger so that it will receive an ordinary nickel or five centpiece. Pivotally supported by the plate 20, the front plate 51 and a bushing 55 carried by the plate 20is an operating shaft 56 which has secured thereto forwardly of the front plate 51 an operating handle 57. The operating shaft and handle may be conveniently formed of one piece bent at right angles as shown in the drawlugs.

Rigidly secured to the other end of the operating shaft 56 is a segmental gear 58 29 on therod 27. When the handle member 57 is rotated in a counter clockwise direction as shown in Fig. 1 the segmental gear 58 will be rotated .11? In Sal].

mechanism which is adapted to deliver one newspaper at a time from a pack of news papers resting on the support 49.

In order ,to prevent the operation of the slide 27 until after a coin or a plurality of coins have been inserted the following lockin means areused. The locking plate 32 re erred to above extends from the slide 27 toward plate 20 as will be clear from Fig. 8 of the drawin s. This locking plate is provided with t ree openings 59, 60 and 61 which openings differ in diameter as will be clear from Fig. 8, the opening having the smallest diameter being positionedv to the left adjacent an elongated slot 62 formed in the locking plate. At the right hand end of the slot 62 as shown in Fig. 8 provided a downwardl curved cam portion 63 the purpose of which will be described later. The left hand end of the locking plate as shown in Fig. 8 is also curved Adapted to cooperate with the openings M 59, 60 and 61 are three locking bolts 65, 66

and 67. These bolts having diameters corresponding to the respective openings in theloo 1 plate 32 and are adapted to engage locking plate 32 are in normal osition.

openings when the slide 27and the The bolts are adapted to slide vertically in a suitable housing 68 which housing is conveniently formed in two arts 69 and 70. The upper part 69. and t e lower part 70 are held in fixed vertical alinement by means of the screws'71 shown in Fig. 7 of the drawings. Extending vertically through the garts 69 and 70 are three bores or openings 2, 73 and 74 which openings .are adapted to slidably receive the three locking bolts previously referred to. The

upper part 69 is also provided with trans versely extending slots 75, 76 and 77 which slots aline with. the respective slots 52, 53 and 54 inthe front late 51 described above. The lower ends of t e bores are enlarged as shown at 78in Fig. 7 in order to provide space for the vertical movement of shoulders 79 which are formed on the respective locking bolts. Coil springs 80 are interposed between" the shoulders 79 and the A removable plate 81is secured to the lower end of the part 70 and has three openings accommodating the ends of the locking bolts.

Each of the locking bolts has a cut away portion 82 which cut away portion extends substantially one half way across the looking bolt as will be clear from Fig. 9 of the drawings so that each bolt is semi-circular 1n the crosssection at the cut away portion.

The cutaway portion provides a lower shoulder and an upper inclined shoulder 8t on each bolt. Interposed between the parts 69 and 70 is a plate 85 which is shown in plan view in Fig. 9 of the drawings. This plate has at its ends openin to receive the screws 71 and is rovi ed with three substantially semi-circul ar notches 86 which engage the cut away portions of the locking bolts as shown in Fig. 9. The plate 85 therefore prevents rotation of the looking bolt but permits them to slide vertically. The shoulders 83 engaging the lower surface of the plate 85 limit the upward movement. of the locking belts in the housing 68. The space between the plate 85 and the upper shoulder 84 on each locking bolt is sommvhat less than the diameter of the coin to be used to release the respective locking bolt. When the coin is inserted through one of the slots in the front plate-51 it engages the shoulder 84 on the bolt adjacent said slot and moves the bolt -upwardly against the action of the spring 80. This upward movement of the bolt will result in withdrawing the lower end of the bolt from the respective opening in the locking plate 32. If all three of the locking bolts are in operation it will be necessary to insert three coins in order to release the slide 27 and the locking plate 32. bolts is held out of operation only two coins will be required.

Rigidly secured by means of screws 87 to the part 70 ot' the housing is a guide 88 which guide has extending vertically therethrough three openings 89, which are adapted to accommodate three pins 90which pins slide vertically in the openings. Each pin is provided with laterally extending fingers 91 which extend into slots 92 which extend across the upper ends of the openings 89. The fingers 91 and the slots 92 prevent the pins from rotating in the openings 89. The upper end of each pin is inclined downwardly as shown at 92 in Fig. 5.

Fixedly secured to the operating shaft 56 is a plate 93 which is preferably shaped as shown in Fig. 7 of the drawings. This plate is adapted to swing upwardly around the shaft 56 as a center in a recess 94 formed in the door 13 adjacent the plate 20. The plate 93 has a beveled upper edge 95 which is adapted to engage the coins and move them inwardly as the plate is swung u wardly by means of the handle member If one of the locking The bar 96 is positioned above the fingers Y 91 so that it will prevent'the fingers moving upwardly further than shown in Fig. 3. v

In Figs. 10 and 11 I have shown means for holding one orinore of the locking bolts in inoperative position when it is desired to operate the machine with less than the entire number of coins. This means comprises a plug portion 97 whose dimensions are equal to the diameter and thickness of the coin to be used. The plug portion carries a shield portion 98 which is adapted to fit across the slot in the front plate 5-1 as is shown in Fig. 10. After the locking bolt in question is raised to the position shown in Fig. 10 the plug 97 is inserted beneath the shoulder 84 as shown in Fig. 1.

A key99 is then inserted through a suitable opening in the rear end of the pin portion 97. The key engages the rear wafi of the housing 68 and prevents removal of the plug and shield. In Fig. 3 I have shown an alternative means for holding any desired locking bolt in inoperative position. This means comprises a hook 100 pivotally mounted upon the inner surface of the door 13 and adapted to engage a suitable openin 101 formed in the upper end of the locklng bolt. When the bolt is raised the hook may be inserted in the opening 101 and will hold the bolt in an operative position. It will, of course, be understood that a hook 100 may be provided for each locking bolt if so desired. The advantage of using the device shown in Fig. 11 is that the slot will be closed when the bolt is held in operative position whereas if the hook 100 is used additional means would also have to be used to close the slot in question.

The operation of my device is as follows: Let it be assumed that Sunday papers are to be sold at the price of seven cents each. The three locking bolts will then be left in operative position. If the operator desires to purchase a paper he will insert one cent pieces in the slots 52 and 53 and a five cent piece in the slot 54. After the coins are inserted they will assume the position shown in Fig. 5 wherein they rest upon the plate 85 and against the pins 90. This releases the slide 27 so that the operator may turn the handle 57 in a. counter clock wise direction as shown in Fig. 1. This movement of the handle member causes the segmental gear 58 to move the slide 27 to the left in Fig. 2. The plate 93 will swing upwardly and the beveled edge 95 will engage the coins and move them inwardly the handle back to normal position.

to approximately the position shown in Fig.

102. At approximately'the same time that the last pin 90 drops off the locking plate, the roller 44 rides off the cam .45 and the I spring 41 swings the pronged member 43. into contact with the foremost paper. Further movement of the slide 27 will cause one end of the paper to be drawn out from behind one of the rods 50. When the slide; has reached the limit of its, movement toward the left in Fig. 2 the operator swinTgs. 8. prong on the member 43 will continue to hold the paper and will draw it out'from behind the second rod 50. When the paper is released from the second rod .50 the roller 44 engages the upwardly. inclined portion 46 of the cam 45 and the member 43 will be drawn away from the paper as shown in Fig; 4. The paper WlllthGIl drop down and out through'a suitable slot in the bottom of the machine. 1

After the coins have been released as described above the springs will force the locking bolts downwardly as shown in Fig. 7. As the slide 27 'returnsits movement will be toward the right in Fig. The downwardly turned end 64 of the locking plate will pass beneath the lower end of the locking bolt 65 shortly after the slide begins its return movement. The. locking bolt 65 will therefore drop into the slot 62 and will prevent the operator from again moving the slide to the left in Fig. 7. Upon further movement of the slide toward the right in Fig.7 the second and third pins 66 and 67 will drop consecutively into the slot 62 and this will insure a complete return movement of the slide. As the. slide moves still further toward normal positionv the cam portion 63 on the slide will pass successively beneath the lower ends of the locking bolts. As the locking bolt 65 is of larger diameter than the opening 61 it will not drop into said opening nor will it drop. into the opening 60 for the same reason, Likewise as the locking bolt 66 is of larger diameter than the opening 61 it will not drop in to the opening 61. The locking bolts will therefore slide over the top of the locking plate until the locking plate reaches its normal position whereupon the locking bolts 65, 66 and 67 will be in exact alinement with their respective locking openings59. 60. and 61 and will drop therein to again lock the slide in normal position. If it vis desired to sell a paper for six cents the slot closin member shown in Fig'. 1l will be inserte in the slot52. If the paper is to besold for two cents a slot closing member like that" shown in Fig. 11 will be inserted in slot 54. If the price isto be only one cent then two of the locking bolts will be held out of operative position.

Itwillbe noted" wardly as shown inlFi'g. 5' after'it is inserted and as the coin completely closes the slot inthe housing it will be practically impos sible to extract thegcoin once it is insrtedQ Th 'forwardedges of the inclined shoulders"- 84 aresharp enough to bite into a lead slug or any other slugmadeof soft material and" will eflectively1prevent the use of such slugs. Thepanel 19 has a depression formed therein to receive the housing 68 and the housing is securely held in position by means ofscrews 103clearly shown. in Fig.3: of the drawings. .When the plate93" is swung upwardly to the position shown in dottedflines in Fig.7 it completely closes all of" the coin from Figs. 5: and 6'. that 3 plate 85 is positioned slightly lower than the lower edge of. the slotsin; the front plate 51. Thefcoin will therefore drop dowm.

slots and will prevent the insertion of coins" or slugs while the machine is beingqop'erated.

. The beveled edg'e 95hpassing close behind the plate20 will shear or out 01f any strings which may be attached to the coin's for the purpose of withdrawing. them afteroperas, tion.-', Having .thusd'escribed my invention what I claim asnewj'anddesire' to secure by United States Letters Patent is:
